- Paper clay
Paper clay (sometimes referred to as fiberclay) is any
clay body to which processedcellulose fiber (paper being the most common) has been added. [Paper clay should be distinguished from Paperclay, aka Creative Paperclay, which is an air hardening modeling material popular within the recreational arts, crafts, puppet and doll-maker communities. This modeling material actually contains no clay. Paperclay is a registered trademark with the U.S. Patent and Trademark Office. Registration No. 1814872.] Clays that have been converted to paper clay includeearthenware ,terra cotta ,stoneware ,porcelain , andbone china .Firing temperatures for paper clay are exactly the same as the clay body from which the paper clay was made. Some recommend slightly higher firing temperatures. Because the paper clay is porous and strong when dry, [cite web|url= http://www.grahamhay.com.au/juvonen1997.html|date= June 1997|accessdate= 2007-12-14| title= "Using paper fibre as a substitute in ceramic clays" by Leena Juvonen|work= 8th CIMTEC World Ceramics Congress.

There is no physical difference between soft clay and the same clay as a soft paper clay, except the small fibers. Building techniques used with soft paper clay are similar to conventional clay. Dry paper clay is stronger than the same clay without the fiber, enabling thinner, more delicate works.
The inclusion of processed cellulose fiber in the clay enables new ceramic techniques. Joining dry-to-dry paper clay and dry-to-soft paper clay are the most radical new techniques. A new aesthetic has also emerged from combining paper and clay art traditions.
